Abstract: ABSTRACT OF THE DISCLOSURE     A piston, lead screw, dispenser rear end wall and twistable projection are assembled together.  On the filling line, tubes each with a dispenser spout at one end, are filled through the opposite end and closed by securing the rear end wall of the assembly to the tube as a closure for the open end.  In one embodiment the tube and end wall are made of plastic material and the securement is by ultrasonic welding; in another, the tube is of foil/fiber composite, the end wall is of metal and the securement is accomplished by crimping.  When the dispenser tip is opened, rotatably twisting the lead screw projection in one angular sense will advance the piston and discharge the tube's filling of caulking compound or the like, that is contained between the piston and the spout.

Abstract: CLOSED LOOP EXHAUST GAS RECIRCULATION SYSTEM         ABSTRACT OF THE DISCLOSURE   A closed loop exhaust gas recirculation system for an internal combustion engine having an intake system, an exhaust manifold, a throttle disposed within the intake system for controlling air flow therein, a conduit coupling the exhaust manifold to the intake system for supplying exhaust gases back to the intake system for controlling the generation and emission of oxides of nitrogen and for improving driveability . The system includes a first memory pre-programmed with a look-up table of optimal values of absolute manifold pressure (MAP0) as a function of engine speed (RPM) and throttle position (.theta.). The actual operating parameters of absolute manifold pressure (MAP), engine speed (RPM) and throttle position (.theta.), or alternatively air flow (AF), areaccurately sensed. The actual values of throttle position or air flow and RPM are used to address the first memory which outputs the pre-programmed optimal value of MAP. The actual value of throttle angle or air flow may be compensated for ambient barometric pressure and/or altitude, if desired. The actual value of MAP is compared with the optimal value of MAP0. The output of the comparator is used to close the loop and control the position of a valve positioned at least partially: within the conduit such that the amount of recirculated exhaust gas (EGR) supplied to the input system is increased if MAP < MAP0 and the amount of EGR is decreased if MAP > MAP0.

Abstract: MULTI-SECTION FOLDING TOOL BAR FOR AGRICULTURAL IMPLEMENTS         ABSTRACT OF THE DISCLOSURE         A folding sectional tool bar for agricultural implements and including a series of articulated hollow sections connected together in end-to-end fashion so as to provide an inner main-section, a pair of outer sections, and a pair of intermediate sections.  An offset hinge joint between each outer section and its adjacent intermediate section permits them to be latched in an aligned working arrangement and allows generally horizontal folding of the outer sections forwardly relative to the adjacent inter-mediate sections.   An offset hinge joint between each intermediate section and its adjacent main section permits the intermediate sections to float down about 5° relative to the main section and allows vertical folding of the inter-mediate sections relative to such main section.  Hydraulic means are provided whereby an initial partial fold of 5° intermediate sections can elevate them relative to the inner main section to an angle of about 5° in order to withdraw such earth-working tools as may be carried by the outer sections from ground contact.  The entire tool bar can then be raised by the tractor hitch and if it is desired to fold the tool bar it is followed by full effective forward fold-ing of the outer sections.  Thereafter, full effective upward folding of the intermediate sections with the outer sections remaining folded thereon is resorted to, thus bringing the articulated tool bar as a whole to its fully folded position to attain a materially reduced width for purposes of transportation as well as a reduced height incident to the forward folding of the outer sections.

Abstract: A TECHNIQUE FOR THE DETECTION OF FLAT WHEELS       ON RAILROAD CARS BY ACOUSTICAL MEASURING MEANS            ABSTRACT OF THE DISCLOSURE   Method and apparatus for detecting the presence of flat wheels on railroad cars, comprising an electro-acoustic transducer located on the track wayside so as to pick up the vibrations generated by a passing train.  If a flat wheel is present it will generate a periodic clanging sound at a frequency proportional to train speed and wheel diameter.  The invention capitalizes particu-larly on the measurement of train speed to control the response of an adaptive filter so as to enhance the periodic clanging frequency with respect to the background noise, thereby to improve the signal-to-noise ratio; the enhanced signal is further autocorrelated for ten wheel revolutions and if a periodic signal is present in the narrow frequency band of interest, a large periodic autocorrelation output will result and, as a consequence, any wheel flat will be readily detected and will act to trigger an alarm to alert the train crew of the condition.
